Dr. Sachiko McBride's squirrel, Half-tail, rides a skateboard. She starts down a hill with her skateboard from the rest and reaches her final speed of 12 m/s at the bottom of the hill in 9.5 seconds. What is the acceleration of Half-tail? You bought a new 2022 Honda Civic and drove it on US 60 at a velocity of 20 m/s. You suddenly get into a heavy rain storm and now it becomes hard to see so you leave a large space between you and the vehicle in front of you. Oh no, an accident happens! The vehicle in front of you collides with a truck! You immediately apply the brakes and slow down with a magnitude of acceleration of 15 m/s² to avoid hitting the vehicle and the truck and save your new Honda Civic. (A) How much time is needed for your vehicle to stop? (B) If you are 15 m from the vehicle in front of you when the accident happens, how close does your Honda Civic come to the vehicle in front of you when your vehicle stops? Chameleons stretch their tongues when they capture insects. The chameleon can extend its tongue up to 27 m/s from the rest in 0.010 seconds. (A) Find the magnitude of acceleration of chameleon's tongue. Assume its acceleration is a constant. (B) How long can the chameleon stretch its tongue in 0.010 seconds? The driver of a snow plow heading West pulls off into an emergency turn around on US-60 so that he can turn around and plow the eastward moving side of the interstate. The snow plow driver patiently waits for a break in the traffic until he can merge into the eastward moving traffic. In order to successfully merge with constant acceleration, the snow plow starts from rest, moves in a straight line, and has a speed of 24 m/s when it reaches the end of the merge lane, which has a total length of 98 m. (A) What is the magnitude of the acceleration of the snow plow? (B) How much time does it take the snow plow to travel the full length of the merging lane? (C) The traffic on US-60 is moving at a constant velocity of 24 m/s. What distance does the traffic travel while the snow plow is moving the length of the merging lane?
